Almost 100% WiFi

Over the summer we finished the final phase of our wireless deployment, making the entire campus – every square inch of it.    So when I saw these poor, abused cables….

NetWare 7 – Futures and Roadmap

Friday, July 1st, 2011

With Novell TTP Conference in Provo next week and Brainshare in Salt Lake City just a couple months after, there is much speculation as to the implications of the Novell acquisition.   These events represent “first contact” with the new management teams, and give us a window into the sentiments of Novell employees and customers.   But if the  following picture gives us any hints,  its bound to be one heck of an event!

Netware 7?   What is Novell thinking?  Perhaps Attachmate execs see there is some value left in the NetWare brand, or perhaps re-badging, in a literal sense,  of the OES product line is in the future?   Or perhaps they are understanding “legacy” means mature, stable, and reliable.   In an era where IT infrastructure is harder to defend, the alien nature of NetWare enhances its suitability for hardening the assets in the data center.

I don’t know, but I can say that I will be watching both of these events carefully.   NetWare 7?   How bad can it be?

Helioscope – Second Light

Wednesday, June 15th, 2011

Finally got the sun and the helioscope together and has a few minutes to play and adjust.  Its FAR from a usable instrument.   But here are the preliminary results.   Here is the actual sunspot imagery from NASA’s hundred million dollar SOHO satellite.   It shows two “small” sun spots   This represents the best possible images one could hope to achieve.

I’ve found a solution to my rabbit problems.   And since I am humane, I’ve posted the sign at rabbit eye level.

HP’s WebOS, Ready for the “Angry Birds Enterprise”

Tuesday, May 31st, 2011

HP has been pushing their WebOS pad computer as an enterprise ready tool.   Its all about the enterprise. But HP has an interesting concept of “enterprise” applications in pushing their WebOS based tablet offering:

What would, indeed, be incredible…  using Angry Birds as a front end to common enterprise applications, like CRM and ERP.   The trick is to find an appropriate data model that translates birds, pigs, and oddly fragile fortresses into customers, trouble tickets, and resolutions.

Another Stacking Comparison

Tuesday, May 31st, 2011

Here is another stacking comparison.   Here is the original S100fs 400 ISO, 4 sec. exposure.   Its pitch black.

After normalizing the histogram to push the exposure it amplifies the noise:

As youc an see, the Fuji noise reduction struggles to make sense of the inky image.   But this 100% crop, craptastic as it is, … oh heck, its terrible.   But stacking 10 of them gives a less craptastic image that is somewhat usable and demonstrates the utility of stacking.   Considering we are taking a noisy small sensor camera and pushing it 3 to 4 stops – this isn’t bad.

Its still a noisy mess, and the Fuji NR artifacts abound, we have improved the SNR to the point where stars are visible as well as some hot pixels ( the tiny white centered donuts.   But these can be removed via dark frame subtraction.

 

Image Stacking vs Cheap Cameras

Friday, April 29th, 2011

Even the images from cheap cameras can be stacked resulting in significant reductions in noise.   For example, from left to right: original image, stacking 3 images, stacking 6 images.   Click to see details…

Firefox Colors All Messed Up

Thursday, March 31st, 2011

After updating to the latest Firefox 3.6.16 and 3.6.17 as well as testing 4.0 certain images would display psychedelic colors – but only on some images.  It did not seem to matter if they were .png, .jpg, or if they were simple or complex.   For example the background in Firefox, the foreground is GIMP display the same file:

Wow, who knew you could use Firefox as an artistic filter.  For more examples and a fix… (more…)

Getting Burnt… Pellet Quality

Sunday, January 30th, 2011

The burning season is almost at an end, while I’m impressed by the progress in the stove technology, the quality of pellets is somewhat less sparkling.    Since it has been 20 years since my last pellet stove experience, I decided to purchase pellets by the bag this time around.   The idea was to try various brands in the stove, gauge the amount of pellets used, so as to make a smarter bulk purchase in future seasons.   Here are some brands I tried in our Quadrafire Mt. Vernon AE…
